No doubt Warners is feeling confident in the Oscar-nominated and Emmy-winning McCarthy's drawing power after she helped the studio's February comedy
"Identity Thief" outperform expectations and become one of the few genuine hits so far in 2013.

While the move is unlikely to faze Disney, the question now is whether or not Sony blinks considering the far more mixed track record of both Diaz and Segel at the box office.

"Tammy" stars McCarthy as a recently unemployed woman who discovers her husband has been cheating and takes off a road trip with her boozehound grandma.
Kathy Bates, Susan Sarandon, Mark Duplass, Dan Aykroyd and
Allison Janney co-star. McCarthy also co-wrote the script with her husband, actor
Ben Falcone who will also make his directing debut on the project.
